Struct Documentation

template<typename Result>
struct Sequencer

A Sequencer accepts a function that yields the next result of a DataLoader and then has the opportunity to influence the order in which these results are returned.

The NoSequencer does not enforce any sequencing and returns any result directly. The OrderedSequencer instead buffers results internally to return them in order of their sequence number.
